Abstract: Following the description of the subsided land treatment methods and the characteristics of the related land reclamation, the necessity and emergency of the land reclamation work is stressed. To cope with the related problems, dynamic prediction of the ground subsidence in different time periods and areas is made based on the laws governing the rock and ground movements and line with a mine’s future mining plan. It is proposed to carry out dynamic management of subsided land reclamation work in mining area, in order to tackle the previous and current issues confronted in the processes of land requisition, compensation and land reclamation. It is intended to provide, through the above-mentioned efforts, the technical and decision-making basis for the mining authorities concerned to better solve the problems relating to land requisition and reclamation in the future, and relocation of villages for facilitating the mining of the underground coal depositing and realizing the sustainable development of mining enterprises.
Key words: ground subsidence； dynamic requisition； land compensation； land reclamation
